Propagation Velocities and Growth Rates of Short Large‐Amplitude Magnetic Structures (SLAMS) in the Foreshock of Earth

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Short Large‐Amplitude Magnetic Structures (SLAMS) are believed to play important roles in the physics governing the formation of quasi‐parallel shocks. These isolated non‐linear structures, frequently observed in the foreshock, have been suggested to be building blocks for the shock and have been shown to drive shock reformation. In this work,

Rotational Influence on the Martian Magnetotail Current Sheet: A Multispecies MHD Study

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The Martian magnetotail current sheet exhibits a dawn‐dusk asymmetry, but the reasons for this shift remain unclear. Although crustal magnetic fields influence this asymmetry, most magnetohydrodynamic (MHD) simulations focus on the subsolar orientation of 180°W, 0°N, which places the strongest crustal fields on the dayside and overlooks ...

MMS Observations of Whistler‐Mode Waves: Comparison Between the Observed and Theoretically Predicted Electric Field

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Electric field instruments function by electrically coupling to the surrounding plasma, resulting in a response function that varies depending on local conditions. This variable coupling can complicate quantitative interpretation of wave measurements, yet is rarely considered.

Compression of Mercury's Dayside Magnetopause to the Surface: A Three‐Dimensional Model of Magnetospheric Structure and Dynamics

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We apply a hybrid model (kinetic ions, fluid electrons) to provide context for MErcury Surface Space ENvironment, GEochemistry, and Ranging (MESSENGER) observations of Disappearing Dayside Magnetosphere (DDM) events at Mercury. Such events have been observed on four occasions and are caused by Coronal Mass Ejections completely removing the ...

Intense Ground Magnetic Perturbations During the 2024 May and October Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The May and October 2024 geomagnetic storms represent two of the most intense space weather events of Solar Cycle 25. While differing in global intensity, both storms produced extreme ionospheric disturbances, including equatorward auroral expansion to mid‐latitudes and rapid geomagnetic variations (dH/dt $\text{dH}/\text{dt}$).

Quiet‐Time Equatorial Ionization Anomaly Reversal Observed by the Satellites of Defense Meteorological Satellite Program (DMSP) and Ionospheric Connection Explorer (ICON)

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We investigated the quiet‐time temporal variations of the Equatorial Ionization Anomaly (EIA) and underlying plasma fountain observed in the topside ionosphere during the various F‐region equatorial E × B drift events recorded by the Jicamarca Incoherent Scatter Radar and simulated by SAMI3.
